PIPE-HANGER.

T 0 all whom it may concern:

Be it known that I, ELMER I-I. RoBEnrs, a citizen of the United States,residing at Norwalk, county of Fairfield, State of Connecticut, haveinvented an Improvement in Pipe- I-Iangers, of which the following is aspecification.

This invention has for its object to produce a pipe hanger adapted forgeneral use and especially adapted for supporting steam and hot waterpipes, which shall be so constructed as to permit the hanger to be putup either before or after the pipe is hung, which shall be verticallyadjustable for the purpose of maintaining the alinement of the pipe andwhich shall be free to swing in the longitudinal direction of the pipeas the latter expands and contracts, thus making my novel hangerespecially valuable for sup porting long lines of steam pipe.

With these and other objects in view I have devised the novel hangerwhich I will now describe, referring to the accompanying drawing forminga part of this specitt cation and using reference characters to indicatethe several parts.

Figure 1 is an elevation of my novel hanger partly broken away to showthe construction and also showing a pipe in section; Fig. 2 an elevationfrom a point of view at right angles to the point of view in Fig. 1;Flg. 3 a plan view of the holder detached. showing the hook inengagement therewith; and Fig. 4 is a view of the block detached.

10 denotes a threaded shank which may be suspended from the ceiling inany ordinary 0r preferred manner. I have shown the shank as providedwith ahook 11 which is adapted to engage a suitable holder 12 which isattached to the ceiling. This holder may be an eye or a curved loop, asshown in the drawing. Upon the shank are upper and lower nuts indicatedrespectively by 13 and 14 and between the nuts are a sliding block 15and a sliding cap 16, both block and cap being provided with centralopenings indicated by 17 which are unthreaded and receive the shankfreely. The block is provided with side recesses 18 lying opposite toeach other and top recesses 19 which lead into the side recesses andintothe central opening.

The pipe, indicated by 20, is supported by a spring loop 21, the upperends of which lie in the side recesses in the block and areSpecification of Letters Patent.

provided with inwardly turned ends 22 (one Patented Sept. 27, 1910.

only being shown) which engage the top recesses in the block, (see Fig.l in connection with Fig. The top recesses may be dispensed with ifpreferred but are preferably used in order to increase the rigidity ofthe hanger leaving it to swing freely on the hook. The cap is providedwith arecess 23 which receives the block and the upper ends of thespring loop.

The operation will be readily understood from the drawing.

The hook swings freely in the holder. It is wholly immaterial whetherthe hanger is put up before or after the pipe is hung. In adjusting thehanger to a pipe, the nuts are separated on the shank, the hanger placedabout the pipe as shown in the drawing, the upper ends of the hanger arepressed inward and placed in engagement with the recesses in the block,the cap being raised for the purpose; then the cap is allowed to drop toplace; then the lower nut is turned upward on the shank against theblock to give the required alinement to the pipe, and then the upper nutis turned down ard against the cap to lock the parts of the hangerrigidly in place. Should adjustment of the pipe be required at any timeto preserve its alinement, the nut on the side corresponding with thedirection in which the pipe is to be moved is loosened and the pipe ismoved in the direction required by turning the other nut against it,after which the hanger is locked in place to retain the pipe in its newposition by turning the loosened nut against it.

Having thus described my invention I claim:

A pipe hanger comprising a threaded shank, a supporting block providedwith intersecting top and side recesses, a loop having its ends bentover to fit within said intersecting recesses, a cap having a dependingflange fitting down over the side recesses in said block, said block andcap being free to slide on said shank, a nut on said shank foradjustably supporting said cap and block, and a second nut on said shankcooperating with the first nut to clamp the cap and block together.

In testimony whereof I afiix my signature in presence of two witnesses.
